Abstract:
The technology for processing the HIMS concentrate, including its partial regrinding and drying, mixing, granulating and agglomeration in a high layer, has been developed. A technological scheme for the reconstruction of the Bogdanovskaya sinter plant of the JSC "Pokrovskiy GZK" was developed. Studies have shown that it is impossible to obtain strong, non-destructible (in the process of transportation) and handling granules from this concentrate due to an insufficient amount (6-8 %) of fine particles with a particle size of -0,056 mm, which mainly affect the lumpiness of raw materials. A new technology for the preparation and agglomeration of fine concentrates, including preliminary granulation was developed.
